\fromafm always regenerates mtx file

[Vladimir Volovich]

Hi,

the \fromafm command seems to always regenerate an mtx file; it seems
that it would be better if \fromafm checked whether mtx file already
exists, and only generate it if it does not exist.
(this would be useful e.g. for cyrfinst files with glyph aliasing)

so, if the current behavior (regenerate mtx file each time \fromafm is
called) is not a "must do", then please add a check to the definition
of \fromafm.

	Best regards, -- Vladimir.

P.S. and one more question. consider the following simple file:

\input fontinst.sty
\installfonts
\installfont{test}{cmr10,latin}{OT1c}{OT1}{cmr}{m}{sc}{}
\endinstallfonts
\bye

after running it through TeX, we get in the VPL file:

(CHARACTER D 65 (COMMENT A)
   (CHARWD R 8.0)
   (CHARHT R 6.82996)
   (CHARDP R 0.0)
   (MAP
      (MOVERIGHT R 0.25)
      (SETCHAR D 65) (COMMENT A)
      (MOVERIGHT R 0.25)
      )
   )

(CHARACTER D 97 (COMMENT Asmall)
   (CHARWD R 6.5)
   (CHARHT R 5.45996)
   (CHARDP R 0.0)
   (MAP
      (MOVERIGHT R 0.25)
      (SELECTFONT D 1) (COMMENT cmr10 at 8.0pt)
      (SETCHAR D 65) (COMMENT A)
      (MOVERIGHT R 0.25)
      )
   )

i could understand why extra spaces were added to the Asmall,
but i could not understand why extra spaces were added to A.
(it's now late, so i may be totally wrong, but anyway...;).

Please shed some light. :-)
